Abstract:

To improve the safety of coal production and reduce the production energy consumption, it is necessary to test and evaluate the performance of lots of local fans  running in a coal mine production site. Software processing technology,  sensor technology and  automation technology were used to construct the general structure of the performance testing system for local fans. In addition, the key problems related to this system such as  pressure measurement, flow adjustment, performance curve fitting and software filter were studied. When  practically applied to the developed system, the  accuracy, rapidity and automatic operation of local fan performance test was realized. On this basis, the developed performance automatic test system of AFT-2 local fan was widely used at the  production site, proving the feasibility and applicability of this research result.

Key words: local fan, software filter, performance curve fitting
